WebApr 26, 2024 · For key exchange, it seems to only support Diffie-Hellman group 1, which is 1024 bits in size. This provides an inadequate 80-bit security level and is believed to have been broken by major governments. For the SSH host key algorithm, only ssh-rsa is offered, which is RSA using SHA-1 for signatures. SHA-1 is known to be insecure and collisions ...

In that case, the data is first hashed with HASH to compute H, and H is then hashed with SHA-1 as part of the signing operation. It then goes to define diffie-hellman-group1-sha1, just to show that SHA-1 is indeed the hash mentioned above: thomas hector
